GIMP Taking Too Long to Start (Fonts)

Hi, everyone. I've used GIMP for a long time, and just recently I installed a new OS (Windows 7) on my computer. On my previous OS I had a collection of google fonts that I downloaded (they were numerous), but I never had a problem with startup loading taking so long.

I re-installed the fonts and now GIMP takes about 5-7 minutes to startup. I thought there was a cache that made the loading quicker, but the speed has not increased at all.

Is there anything I can do except deleting the fonts? I need them in GIMP.
